Prediction of the crack growth propagation direction in non-proportional mixed-mode missions

Daniele Amato et al.

Summary: This study proposes two algorithms based on the dominant step criterion to evaluate the crack growth propagation direction under non-proportional mixed-mode loading conditions. They are implemented in two commercial software tools and validated with experimental data. The results show that both software predictions are in good agreement with the experimental results, confirming their validity as tools for simulating crack propagation under mission conditions.

Setting Adaptive Inspection Intervals in Helicopter Components, Based on a Digital Twin

Fubin Zhao et al.

Summary: Setting inspection intervals based on accurate fatigue crack size prediction is crucial for maintaining the integrity of aeronautical structures. However, the current fixed interval inspection strategy faces challenges in managing aircraft with diverse damage states due to uncertainties in fatigue crack growth and prognosis. This study proposes an intelligent crack inspection strategy using a digital twin and a dynamic Bayesian network to adaptively set inspection intervals based on a reduced-order fracture mechanics simulation methodology, a validated fatigue crack growth model, and historical inspection results.

Real-Time Prediction of Probabilistic Crack Growth with a Helicopter Component Digital Twin

Xuan Zhou et al.

Summary: In this paper, a reduced-order simulation approach is developed to achieve real-time prediction of crack growth in complex structures. By combining symmetric Galerkin boundary element method-finite element method (SGBEM-FEM) coupling method with machine learning methods, the proposed approach can automatically simulate hundreds of crack samples and establish the relation between crack sizes/shapes and crack-front stress intensity factors. This method provides a key simulation technology for realizing the digital twin of complex structures.

An X-FEM based framework for 3D fatigue crack growth using a B-spline crack geometry description

Kris Hectors et al.

Summary: This paper presents an X-FEM based iterative framework for numerical simulation of three-dimensional fatigue crack propagation. B-spline curves and surfaces are used to accurately describe the crack geometry, and a new crack front extension method based on the Moller-Trumbore algorithm is introduced. Good agreement between numerical and experimental results validates the effectiveness of the method.

A probabilistic graphical model foundation for enabling predictive digital twins at scale

Michael G. Kapteyn et al.

Summary: This work proposes a probabilistic graphical model as a formal mathematical representation of a digital twin and its associated physical asset, enabling the transition from custom implementations to robust digital twin implementations at scale. The model's declarative and general nature allows for rigorous yet flexible application in diverse areas. Demonstrations show how the model can be instantiated and calibrated with experimental data for dynamic decision-making scenarios.
